Answer:
JK:
Thank you for the tip/donation.
These vehicles do not have a routine service light or indicator, nor does it use the service engine light for that
purpose.
I assume the scanner is working properly and has been checked on another vehicle for its function.
To clarify, is this the service ENGINE light, or the service VEHICLE light?
VISITOR:
It is the "service vehicle soon" message.
Thanks
JK:
There are many different computer systems on todays cars. The service ENGINE indicator is strictly powertrain
computer related. Service VEHICLE codes are stored in the body control module. The service VEHICLE indicator
can be caused by several different systems. Anything from vehicle lighting, to theft system, to body control
module(BCM) to ABS (but usually an ABS light as well), powertrain non-emissions related codes, or
communications problems between any of these computers.
Most inexpensive scanners only read the powertrain computer. In order to read codes that set a service VEHICLE
light, you would need a higher level scanner that can read BCM codes, as well as ABS and others if needed.
About the only thing that can be done without having the BCM scanned is to be sure to check all fuses.
VISITOR:
THE RADIO WORKED FINE UNTIL I CHANGED THE BATTERY. NOW IT IS
LOCKED. HOW DO I UNLOCK IT.
JK:
With a radio replacement, this may very well be the cause of your service vehicle light. After replacing a radio, the
system must be set up with a dealer scanner. Audio system option, VIN #, etc, need to be set up in the radio and
the BCM. If not done, this will cause several different body codes, and is most likely the cause of your service
vehicle light.
If the radio just displays LOC, then you need a Radio Unlock Code.

Question: I have a 2001 Monte carlo and my interior lights won't cut off unless i disconnect the battery. It
runs my battery down.

Answer: I've seen many problems like the one you're having
with your car. What's happening is that the Body Control
Module has an internal failure or short and is keeping certain
electrical circuits powered up. You will need to have the Body
Control Module replaced. It is located under the dash on the
left side. You must have this repair performed at a dealership
because it will need to be programmed and set up to your
particular vehicle. A regular repair shop cannot do this.
